Whats the best stuff to use to waterproof my boots

Try waterproofing? Mine last 12 months if I can keep them dry.

Nope! But if you get wet, put it near a heater or something else hot. It will help you.

I would suggest that you wear any sort of sturdy hiking boot. You want something with ankle support and maybe something waterproof . I don't believe that one type of boot would be "quieter" than another. It all really depends on how you take your steps.

yup! they are waterproof. they are usually made from rubber or PVC.

im not sure if it will harm the material (suede/nubuck?) but supehydrophobic spray will do the trick.

Paint or spray the cardboard with a waterproof coating

• Spray the cardboard with an automotive primer and then let it dry. You can also use a variety of waterproof varnishes to provide this initial waterproof coating for your cardboard. Since you will be painting the cardboard with another layer of protective covering, make sure the substance you use for this initial layer can be painted over.
  Next, paint the cardboard with an outdoor latex paint similar to what you would use on the outside of your house. Having these two layers of waterproof sealant--a primer and a latex--should keep your cardboard stiff and dry for quite a while.

yes you can buy a cleaner and waterproofer in one your best place is from a hiking shop hope this helps

There is not really. Not waterproof. The best solution for that is to buy Marine grade audio equiptment. JBL Marine Audio is the best stuff out there.
